Topaz on Quartz
I have see only a very few blue topaz in matrix from Brazil, and not another such as this, with a sharp blue gem perched on a large quartz crystal! At 8 x 7.5 x 4 cm, the topaz is a good size and significant on its own, and it is literally stuck in a crevasse between two intergrown quartz points. The quartz is terminated, thought etched in back. It is even nearly pristine - just a few very trivial dings mar the large quartz. The topaz itself is pristine and complete all around except for a few very nearly invisible contact points where it attached to another bit of quartz. Even its underside is floating free and clear of the quartz and is roughly terminated, making it a "floater". The top termination is SHARP and has a broad chisel-point termination, leading to razor-sharp, etched side faces. Small bits of sparkling, micaceous-looking lepidolite cling to the center of the topaz and run down its front in a vein , to the quartz. Overall, this is a unique specimen, large and impactful as it sets the topaz high up and easily lit. In fact, the photos do not do it justice. When backlit, the light goes through the quartz and topaz both, and the piece glows. I have not seen another like this, and certainly I feel at the price point, another is unlikely. It could as easily be twice the price, but that I got it reasonably myself in a large specimen, in need of a trim. So we took off a big chunk of massive quartz at the bottom, and now the piece stands quite nicely on its own, and is more balanced.
